IMPROVEMENT IN MOP-HEADS.

Specification forming part of Letters Patent No. 145,958, dated December30, 1873; application filed October 31, 1873.

To all whom it may concern:

Be it known that we, DAVID W. MARSTON and JOHN S. SKINNER, both ofLebanon, in the county of Grafton and State of New Hampshire, haveinvented an Improved Mop-Head, of which the following is aspecification:

Our invention relates to mop-heads, for holding the-swab or mop; andconsists in a novel construction, combination, and arrangement of parts,which have for their object to produce a cheap and effective implement,as will be fully set forth hereafter.

Figure l is a perspective view of our invention embodied in one form.Fig. 2 is a similar view of it in another form; and Fig. 3 is a sec- Itional detail view.

'A A represent the handle of the mop; and B, the cross-head, secured tothe extremity thereof. The stirrup-wire O, which serves to clamp the mopagainst the cross-head B, is bent up, as shown in the drawing.

In Fig. 1, the wire forming the stirrup is formed at its upper portioninto a slot, a a, by the ends of the wire being brought together andcarried up parallel to each other and the handle A. D is a block, whichhas its under surface concave, so as to-fit on the handle of the mop. Eis a clamping-bolt, which is provided with a head, b, at one extremity,and at the otherwith a screw-thread. This bolt passes through the blockD and handle of the mophead. F is a thumb-nut, which works on the screwend of the bolt D. The bolt D passes through the slot a a of thestirrup, and as the thumb-nut is screwed down, the flanged head of thebolt clamps the wires against the block D, and effectually holds thestirrup in place. On releasing the pressure, the stirrup may be slid upor down to accommodate the mop.

Fig. 2 shows another embodiment of our invention, and represents eachextremity of the stirrup-wire bent over into a hook or slot, onesituated on each side of the mop-handle. The wires forming the slots areclamped against the washers on the mop-handle by a clamping devicesimilar to the one shown in Fig. 1, con sisting of the bolt E,constructed with a T-head and screw-thread, a clamping-block or washer,c, and a thumb-nut, F.

It will be perceived on examination that, although the devices aredifierent in appearance, yet the principle of construction and operationis the same in both instances-i. 6., forming the stirrup-wire into aslot, and clamping it against the mop-handle by means of a headed boltand a thumb-nut.

The device is simple, eftectual, and easily manufactured, thereforecheap.

We claim In combination with the handle A and head 13, the stirrup O andclamping device E F, all constructed and operating substantially in themanner described.
